Issue measuring impedances at sample rates other than 30 KHz #2

User reports: I noticed that the sample rate must be set to “30.0 kS/s” in the OE FPGA Acquisition Board in order to measure the impedance. If I change the sample rate to any other values, the RHD2000 Impedance Measurement window stays at “0 %” and doesn’t progress any further at which point I had to restart the GUI.

There also seems to be an issue with channel shifting with a 64ch headstage, when using a rate <30KS/s
